[0030] The people transport system 100 and/or the access control system 120 may comprise only the maintenance interface system 200 according to embodiments of the present invention. In other words, a traditional physical maintenance interface device 116 may be replaced with the maintenance interface system 200 according to embodiments of the present invention. One or more maintenance, test, inspection and/or emergency operations of the system may be carried out via the maintenance interface system 200 according to embodiments of the present invention. Alternatively, the people transport system 100 and/or the access control system 120 may comprise the maintenance interface system 200 according to embodiments of the present invention and the traditional physical maintenance interface device 116 as illustrated in the examples of Figures 1A and 1B. In other words, the maintenance interface system 200 according to embodiments of the present invention may be used to supplement the traditional physical maintenance interface device 116.

The traditional maintenance interface device 116 shall be accessible to authorized persons only. In elevator systems 100, the traditional physical maintenance interface device 116 may be arranged outside the elevator shaft 106, for example inside the machine room of the elevator system as illustrated in the example of Figure 1A or at a landing.
[0031] Figure 2 illustrates schematically an example of the maintenance interface system 200 according to the present invention. The maintenance interface system may provide a visual output representing maintenance related information of the people transport system 100 or the access control system 120 dependent on the system 100, 120 into which the maintenance interface system 200 is implemented. If the maintenance interface system 200 is implemented in the people transport system 100, the maintenance interface system 200 may provide visual output representing maintenance related information of the people transport system 100. Alternatively, if the maintenance interface system 200 is implemented in the access control system 120, the maintenance interface system 200 may provide visual output representing maintenance related information of the access control system 120.
[0032] The maintenance interface system 200 may comprise a storage unit 202 and a user device 204. The storage unit 202 may be for example a computing entity, cloud storage, or other digital media storage or system. The storage unit 202 may have maintenance related information of the people transport system 100 or the access control system 120 stored thereon. The storage unit 202 may be communicatively coupled to the control unit 110a of the people transport system 100 or to the control unit 110b of the access control system 120 in order to be able to obtain maintenance related information of the people transport system 100 or the access control system 120. The communication between the control unit 110a, 110b and the storage unit 202 may be implemented in a wired manner or wirelessly at least in part. According to an embodiment of the invention, the storage unit 202 may be implemented as a part of the control unit 110a of the people transport system 100 or the control unit 110b of the access control system 120. According to another embodiment of the invention, the storage unit 202 may be an external storage unit. Some non-limiting examples of the external storage units may e.g. be a remote server, cloud server, computing unit, a network of computing devices. The external unit herein means a unit that locates separate from the people transport system 100 or the access control system 120. In the example of Figure 2, the user device 204 is implemented as a set of smart glasses, but the user device 204 may be any other wearable smart device, such as watch; a mobile terminal device, such as mobile phone, tablet computer, etc.; or any other digital user device comprising one or more displays or other capability, such as a projector, to display the maintenance related information according to the embodiments of the present invention as will be described.
[0033] Now, at least some aspects of the present invention may be described by referring to Figure 3 in which a method according to an embodiment of the present invention is schematically illustrated.
[0034] In the step 310 an activation event may be detected. The detected activation event may be manual activation or automatic activation. The detection of the manual activation event may be a detection of a user indication. The user indication may be provided for example via the user device 204, e.g. user interaction with the user device 204 and a user, e.g. a maintenance personnel, of the user device 204. The use device 204 may comprise one or more input devices, such as buttons, touchscreen, touch-buttons or similar, for providing the user indication indicating activation of the user device 204. For example, the manual activation event may be a touch, e.g. with a finger or any other pointer, on a touch button of the user device 204.
[0035] Detecting the automatic activation event may comprise detecting a location of the user device 204. In other words, detecting the automatic activation event may comprise detecting that the user device 204 resides, i.e. locates, at a predefined location. The predefined location may be for example a machine room; a service center; an environment of the people conveyor system 100 or access control system 120; e.g. a specific landing in an elevator system; any other location suitable for performing maintenance operations. The location detection may be based on any indoor positioning system; Global Positioning System (GPS) or any other outdoor positioning system; any visual image recognition system; a digital readable optical code system, such as barcode, QR code, or any other digital readable optical code; or a radio-frequency system, such as a radio-frequency identification (RFID) system or any other RF-based solution. For example, the user device 204 may detect the automatic activation event by detecting that the user device 204 locates at the predefined location by using any indoor or outdoor positioning system or any visual image recognition system. Alternatively, the user device 204 may comprise scanning and/or reader devices capable to scan and read the digital readable optical code and/or an RFID tag. The digital readable optical code and/or RFID tag may be arranged in the predefined location. The user device 204 may detect the automatic activation event by reading the digital readable optical code and/or the RFID tag.
[0036] Alternatively, detecting the automatic activation event may comprise detecting the user device 204 in a vicinity of the people transport system 100 or the access control system 120, i.e. within the environment of the of the people conveyor system 100 or access control system 120. The user device 204 detection may be based on any visual image recognition system; a digital readable optical code system, such as barcode, QR code, or any other digital readable optical code; or a radio-frequency identification (RFID) system. For example, the user device 204 may comprise scanning and/or reader devices capable to scan and read the digital readable optical code and/or RFID tag. The digital readable optical code and/or an RFID tag may be arranged at a suitable location within the environment of the of the people conveyor system 100 or access control system 120. The user device 204 detects the automatic activation event in response to reading the digital readable optical code and/or the RFID tag.
[0037] In the step 320 the user device 204 may receive at least part of the stored maintenance related information from the storage unit 202 in response to detecting the activation event. The maintenance related information may comprise, but is not limited to, equipment data; maintenance history data; instructions and documentations, recommended maintenance actions, e.g. based on remote data analysis, data from one or more sensors, usage data, or any other kind of analytics based data, calendar based maintenance or other planned maintenance; equipment type or model; performance data, operational parameters of the system; and/or real time or delayed video image from one or more imaging devices, such as cameras, arranged on site.
[0038] In the step 330 the user device 204 may provide a visual output 410, i.e. a display, representing the received maintenance related information by the user device 204. The user device 204 may display the received maintenance related information e.g. on the one or more displays of the user device 204 or through projection by the projector of the user device 204. The provided visual output 410 may act as a digital maintenance interface device of the people transport system 100 or the access control system 120. With the term "digital maintenance interface device" is meant throughout this application a user interface displaying the received maintenance related information, wherein the user interface is not a physical maintenance interface device, such as a maintenance access panel, of the people transport system 100 or the access control system 120. The visual output 410 may be created, i.e. implemented, with augmented reality (AR), virtual reality (VR), or mixed reality (MR). Alternatively, the visual output 410 representing the received maintenance related information may be displayed on the one or more displays of the user device 204, such as a mobile phone, a tablet computer, a smart watch, or any other digital user device comprising one or more displays or other capable to display the visual output 410. This enables a simple way to provide the visual output 410.
[0039] In the augmented reality the visual output 410 representing the received maintenance related information, e.g. augmented reality display, may be overlaid on a real-world environment. The visual output 410 implemented with augmented reality display, i.e. augmented reality interface, may be placed virtually on any surface or location. The augmented reality display may e.g. be a see-through augmented reality display or a projected augmented reality display. The see-through augmented reality display may be displayed on a display or a screen of the user device 204, such as a video see-through display or a holographic based see-through display. The projected augmented reality display, i.e. spatial augmented reality display, may be projected on a wall, a panel, or any similar surface. The augmented reality display may be relative to the view of the user of the user device 204, relative to the user device 204, or floating in a static spatial location, i.e. relative to spatial direction. An augmented reality display being relative to the view of the user of the user device 204 means that the augmented reality display is in the same place in relation to the user, when the augmented reality display is activated. In other words, when the user turns their head, the augmented reality display moves accordingly so that the reality display is in the same place in relation to the user. For example, e.g. the augmented reality display may be at a predefined distance from the head of the user, when the augmented reality display is activated, e.g. at a one meter distance from the head of the user. According to an example, if user device 204 is a mobile terminal device, e.g. a tablet computer, when the user places the mobile terminal device in front of their face the augmented reality display may be visible, but if the mobile terminal device is lowered and directed, e.g. by the user of the mobile terminal device, e.g. towards floor, the augmented reality display may no longer visible. An augmented reality display being relative to the user device 204 means that the augmented reality display is in the same place in relation to the user device 204, when the augmented reality display is activated. In other words, when the user device 204 is moved e.g. by the user of the user device, the augmented reality display moves accordingly so that the reality display is in the same place in relation to the user device 204. For example, e.g. the augmented reality display may be at a predefined distance from the user device 204 at a predefined direction, when the augmented reality display is activated, e.g. at a one meter distance from the user device 204 in front of the user device 204. According to an example, when the augmented reality display is pointing to floor the augmented reality display may still be the predefined distance from the user device 204 to the predefined direction, e.g. one meter from the user device 204 in front of the user device 204 somewhere above the floor. An augmented reality display being relative to spatial direction means that the augmented reality display may be floating in a predefined physical location, when the augmented reality display is activated, irrespective location of the user of the user device 204. In other words, the augmented reality display may be floating in a corner of a floor irrespective of a direction from which the user of the user device 204 is looking at the augmented reality display. The visual output 410 implemented with augmented reality may be operated on site, i.e. the user device 204 (and the user of the user device 204) may be in a vicinity of the people transport system 100 or the access control system 120 when operating the maintenance interface device implemented with augmented reality, or remotely, i.e. the user device 204 does not need to be in vicinity of the people transport system 100 or the access control system 120, when operating the maintenance interface device implemented with augmented reality.
[0040] In the virtual reality the visual output 410 representing the received maintenance related information, e.g. virtual reality display, i.e. virtual reality interface, may be arranged to replace a real-world environment with a virtual environment. Otherwise, the virtual reality operates as the augmented reality described above. The visual output 410 implemented with virtual reality may be operated on site. Preferably, the visual output 410 implemented with virtual reality may be operated remotely.
[0041] In the mixed reality real-world objects may be dynamically integrated into virtual world to produce new environments and visualizations, where physical and digital objects, such as the visual output representing the received maintenance related information, e.g. a mixed reality display, i.e. mixed reality interface, may co-exist and interact in real time. Otherwise, the mixed reality operates as the augmented reality described above. The visual output 410 implemented with mixed reality may be operated on site or remotely.
[0042] Figures 4A to 4C illustrate example embodiments of system according to the present invention. Figure 4A illustrates an example embodiment, wherein the user device 204, i.e. smart glasses in this example, is arranged to provide the visual output 410 representing maintenance related information, which is received from the storage unit 202 in response to detecting the activation event. For sake of clarity the user of the user device 204, equipped with, i.e. wearing, the user device 204 is not illustrated in Figure 4A. The provided visual output 410 in the example of Figure 4A is augmented reality display, but the provided visual output 410 may alternatively be virtual reality display or mixed reality display. The augmented reality display of the example of Figure 4A is see-through augmented reality display, but the augmented reality display may alternatively be projected augmented reality display. The provided visual output 410, i.e. the displayed received maintenance related information, may comprise one or more elements 412a-412n each being associated with at least one piece of the received maintenance related information. In other words, each element 412a-412n may represent at least one piece of the received maintenance related information. Some of the elements 412a-412n may be associated with at least one piece of the received maintenance related information enabling providing output information to the user, e.g. the elements 412a-412c in the example of Figure 4A. Some of the elements 412a-412n may be associated with at least one piece of the received maintenance related information enabling interactive operations to receive, i.e. detect, user indication from the user, e.g. the elements 412d-412n in the example of Figure 4A. The provided visual output 410 and/or the elements 412a-412c of the visual output 410 may comprise, but not limited to, text, words, tables, graphs, buttons, gauges, switches such as slider switches, rotating wheels, light indicators, images, video images, and/or animations, etc. The size of the provided visual output 410 may be scalable according to displayed content, e.g. number or displayed elements 412a-412n.
[0043] Figure 4B illustrates another example, wherein the user device 204, i.e. mobile phone in this example, is arranged to display on the display of the user device 204, e.g. touchscreen of the mobile phone, the visual output 410 representing maintenance related information, which is received from the storage unit 202 in response to detecting the activation event. In the example of Figure 4B, the visual output 410 displayed on the display of the mobile phone 204 comprises elements 412a, 412c being associated with at least one piece of the received maintenance related information enabling providing output information and element 412d being associated with at least one piece of the received maintenance related information enabling interactive operations causing that the visual output 410 may be capable to provide output to the user and/or to receive user indication from the user. Figure 4C illustrates another example, wherein the user device 204, i.e. smart watch in this example, is arranged to display on the display of the user device 204, e.g. a screen of the smart watch, the visual output 410 representing maintenance related information, which is received from the storage unit 202 in response to detecting the activation event. In the example of Figure 4C, the visual output 410 displayed on the display of the smart watch 204 comprises only elements 412a, 412c being associated with at least one piece of the received maintenance related information enabling providing output information causing that the visual output 410 may be capable only to provide output information to the user, but not receive any user indication from the user.
[0044] The part of the maintenance related information received by the user device 204 in the step 320 from the storage unit 202 may depend on an access level assigned for the user device 204. The user device 204 may be capable to have different access levels indicating different level access rights for the user of the user device 204. Different amount of the maintenance related information and/or content of the maintenance related information may be received from the storage unit 202 for each access level assigned for the user device 204. The access level may be device specific and/or user specific. Device specific access level means that each user device 204 may have a specific access level irrespective of the user of the user device 204. The user specific access level means that each user may have a specific access level. This enables that the same user device 204 may have different access levels for different users of the user device 204. According to an example, unauthorized user, an operator of the people transport system 100 or the access control system 100, and a maintenance personnel may each have different access level for the user device 204 causing that different amount and/or content of the maintenance related information may be received from the storage unit 202 for each access level. Figure 5A-5C illustrate non-limiting example views of the provided visual output 410 with different amount and/or content of the maintenance related information received by the user device 204 from the storage unit 202 depending on the access level assigned for the user device 204. Figure 5A illustrates an example view of the visual output 410 provided for an unauthorized person having a first access level, e.g. a lowest access level, for which no maintenance related information can be received at all causing that the provided visual output 410 comprises an empty display. Figure 5B illustrates an example view of visual output 410 provided for the maintenance personnel having a second access level, e.g. an intermediate access level, for which a first part of the stored maintenance related information may be received causing that the provided visual output 410 represents the first part of the stored maintenance related information. Figure 5C illustrates an example view of visual output provided for the operator having a third access level, e.g. a highest access level, for which a second part of the stored maintenance related information may be received causing that that the provided visual output 410 represents the second part of the stored maintenance related information. The second part of the stored maintenance related information may be at least partly different from the first part of the stored maintenance related information. For example, the visual output 410 provided for the operator may comprise information relating to one or more operations of the people transport system 100 or the access control system 120 and the visual output 410 provided for the maintenance personnel may comprise information relating to one or more operational parameters of the people transport system 100 or the access control system 120. The different access levels may also enable personalizing of the visual output 410, e.g. appearance or layout. The personalization may comprise e.g. personalized language, personalized location or layout of one or more elements 412a-412n of the visual output 410. Alternatively or in addition, the part of the maintenance related information received by the user device 204 in the step 320 from the storage unit 202 may be adapted or adjusted at any time in order to improve the adaptability of the visual output 410. According to a non-limiting example, if some further maintenance related information is stored into the storage unit 202, the part of the maintenance related information received by the user device 204 in the step 320 from the storage unit 202 may be adapted to include the further maintenance related information.
[0045] Next, at least some further aspects of the present invention may be described by referring to Figure 6 in which a method according to an embodiment of the present invention is schematically illustrated.
[0046] In the step 610, a user indication may be detected, i.e. received. The user device 204 may comprise user one or more input devices, such as touchscreens, keypad, keyboard, buttons, microphones, and/or one or more sensor devices, such as imaging devices, e.g. cameras, accelerometers, gyroscopes, compasses, and/or any other sensor devices capable to detect movement, for detecting the user indication. The user indication detectable with the one or more input devices and/or the one or more sensor device of the user device 204 may comprise at least one of the following: gesture, gaze, voice, touch.
[0047] The touch-based user indication may be detected for example by a touchscreen or touch-based buttons of the user device 204. The visual output 410 may be displayed at least partly, e.g. one or more elements 412a-412n being associated with at least one piece of the received maintenance related information enabling interactive operations, on the touchscreen and/or touch-based buttons arranged to detect the touch-based user indication. For example, in the example of Figure 4B the visual output 410 may be displayed on the touchscreen of the mobile phone 402 and the element 412d may enable interactive operations with the user to detect, i.e. receive, the user indication, e.g. one or more touches with a finger or any other pointer. The voice-based user indication may be detected by one or more microphones of the user device 204. The gaze-based user indication may be detected by one or more sensor devices, such as cameras, of the user device 204.
[0048] The gesture-based, i.e. motion-based, user indication may be detected by one or more sensor devices of the user device 204, such as cameras, accelerometers, gyroscopes, compasses, and any other sensor devices capable to detect movement. Alternatively, the gesture-based user indication may be detected by one or more sensor devices arranged in a peripheral device such as a pointer, a glove or other wearable accessory. The detected gestures, e.g. gestures of a hand of the user, may mimic physical user interaction with a physical input device. According to a non-limiting example, if the visual output 401 comprises one or more elements 412a-412n being associated with at least one piece of the received maintenance related information enabling interactive operations to receive user indication, e.g. an element 412a-412n representing a switch, button or keypad, e.g. the slide switch 412n of the example in Figure 4A, the detected user indication may be a detection of slide type gesture of the hand of the user at a location of said element 412a-412n, which mimics the sliding of a physical slide switch by the hand of the user. Similarly, in case of element 412a-41n representing any other type switch, keypad, or button, the detected user indication may be a detection of gesture of the hand of the user at a location of said element 412a-412n, which mimics the gesture of the hand of the user using the corresponding physical input device.
